A collection of cutting-edge laboratory techniques for the study of trophoblast and placental biology. The techniques presented range from experimental animal models, to animal and human placental organ and cell culture systems, to morphological, biochemical, and molecular strategies for assessing trophoblast/placental growth, differentiation and function. Volume 1 provides readily reproducible protocols for studying embryo-uterine implantation, trophoblast cell development, and the organization and molecular characterization of the placenta. Highlights include strategies for the isolation and culture of trophoblast cells from primates, ruminants, and rodents, and precise guidance to the molecular and cellular analysis of the placental phenotype. A companion second volume concentrates on methods for investigating placental function.
